The nature of our invention consists in providing the upper part of' a pair ot' doors with two rods of metal, or other material, crossing' each other, and secured to the doors, near the hinges, by joints that are at equal' distanees from eachother, so that by opening one door, motion is communicated to the other equally.

To enable others skilled in the art to make use of our invention, we will proceed to describe its construetiou and operation.

W'e make one or two. bars, A A, with holes at their ends, B B, equal in distance and length to the space between the hinges of the two doors. The rods move on joints or pins fastened over the doors, set at equal distances from 4the hinges.

The joint nearest the inside of the door is connected by the rod A to the joint nearest the outside, so that whichever. door opens, the other acts exactly .the same,

f whether opened inward or outward, or only in one direction.

What we claim as our invention, and desire to secure by Letters Patent, iss- The rods A and their connections B, in combination with the pivoted connection with the door, as shown and described herein, so that the same motion of the one is communicated to the other.
